50 minutes later, Xu Ming led a group of police officers and drove straight to the factory's main gate.
The security guard on duty glanced at the approaching vehicles, and upon realizing they were police cars, did not make any attempt to stop them. He just took a quick look and then relaxed, raising his hand to let them pass.
However, as the police cars slowly entered the factory and hadn't gone far, a middle-aged man wearing black-framed glasses and a neat shirt suddenly walked quickly to the side of the lane, raising his hand to signal the vehicle to stop.
Xu Ming immediately signaled to the driver beside him to hit the brake, bringing the car to a steady stop at the roadside.
He pushed open the car door and got out, asking, "Hello, is there something you need?"
The middle-aged man quickly approached and inquired, "Officer, are you here to further investigate the incident involving Li Mei from a few days ago?"
Xu Ming nodded calmly, not at all surprised by the man's question.
